About Browser Threats
Try this page out on every browser you use so you can see the behavior of each. Test it
out also on mobile as well as on a computer.
The first thing to note is the "fingerprint". As you rerun the test over and over, you
will find that the fingerprint stays the same. Even when you log out, clear cookies, go to
incognito mode, it will haunt you with a fixed fingerprint. The fingerprint is noted
even when on a TOR Browser. But also note that the fingerprint cannot be maintained
when you change browsers. This is why I encourage a technique I call Browser Isolation.
For this test, allow Geolocation on each browser. Compare each browser's ability to geolocate
you using Wifi Triangulation. You will discover that only TOR blocks geolocation. Be aware too that on some browsers you may
not get asked again after giving your information once. This will teach you to turn location off.
Next note your IP address info. For the purposes of this test, we do not do any reverse IP
lookup which can identify your location based on sold aggregated databases. The physical address
for your IP is matched to your ISP's location. Thus, the reality is more dangerous than what is
shown here. Don't be cavalier about the fact that it doesn't show your exact location. At the moment,
purchased databases will point you out typically within 100 feet.
The takeaway here is to use a VPN.
Observe the behavior of the IP address location when you use a TOR browser and see what is
known about you. That will be the same with a TOR browser or TOR Router.
Finally, the last test has to do with Autofill. If autofill is turned on, this test will
show you a vulnerability (tested only on Chrome and Firefox). Select your name if you have
autofill on and see what happens. Does extra information leak? Perhaps you should disable Autofill.
